hello everyone, in december of past year the bitcoin had your historical fall and some people's sayed which the reason was a "tree shaking," others said that increasing fees and delayed transactions made users migrate to other alternatives using others cryptos. Actually some cryptos like Ripple, Stellar, Litecoin and others experienced a good appreciation in this period. Some cryptos offer low fees, more speed in the transations and more facility in low valor transations.

Within this context what you attribute to the recent fall of Bitcoin? 2018 is the altcoins year?
